Chennai/Bangalore, Dec 1: Crossing a major milestone in the country's space history, ISRO's Mars Orbiter mission today ventured out of Earth's sphere of influence for the first time in an attempt to reach the red planet's orbit.

The critical manoeuvre to place the Mars Orbiter Spacecraft in the Mars Transfer Trajectory was successfully carried out almost an hour past midnight.

During this manoeuvre, which began at 00:49 hours, the spacecraft's 440 Newton liquid engine was fired for about 22 minutes providing a velocity increment of 648 metres/second to the spacecraft.

"Following the completion of this manoeuvre, the Earth orbiting phase of the spacecraft ended. The spacecraft is now on a course to encounter Mars after a journey of about 10 months around the Sun," the Bangalore-headquartered Indian Space Research Organization said in a statement.

ISRO performed the trans-Mars injection, a "crucial event" intended for hurling its Mars Orbiter spacecraft into the planned orbit around the Sun, marking the first step towards the 300 day voyage to reach the orbit of the red planet after crossing roughly 680 million kilometer.

"The Trans Mars Injection (TMI) operations, which began at 00.49 hours (IST) completed," ISRO said.

ISRO has planned four mid-course corrections in case of any deviation along its path to the Martian orbit.

The space agency is scheduled to make four corrections in the course of the spacecraft's voyage to Mars before it is expected to reach the orbit of the red planet in September 2014.

It had performed five orbit-raising manoeuvres on its Mars Orbiter, raising the apogee (farthest point from Earth) of the spacecraft to over 1.92 lakh kilometers, before it performed the "mother of all slingshots."

The spacecraft is being continuously monitored from the Spacecraft Control Centre at ISRO Telemetry, Tracking and Command Network (ISTRAC) in Bangalore with support from Indian Deep Space Network (IDSN) antennae at Byalalu here, the space agency added.

ISRO's PSLV C 25 successfully injected the 1,350-kg 'Mangalyaan' Orbiter (Mars craft) into the orbit around the earth some 44 minutes after a text book launch at 2.38 PM from the Satish Dhawan Space Centre at Sriharikota on November 5, marking the successful completion of the first stage of the Rs 450 crore mission.

Mumbai, Feb 9: Given the slow progress on the ongoing Rs 38,000-crore capacity expansion at the four largest metro airports, and also the surging traffic, the snaky queues will continue at least till 2023, warns a report.

The four largest airports -- New Delhi, Mumbai, Bengaluru and Hyderabad -- handle more than half of the traffic and are operating at 130 per cent of their installed capacity. These airports are under a record Rs 38,000-crore capex but the capacity will not come up before end-2023, says a Crisil report.

“With the dip in traffic growth largely behind, we expect congestion at the top four airports of New Delhi, Mumbai, Bengaluru and Hyderabad, which handle more than half of the load, to continue till about FY23,” says the report.

Already these airports are operating at over 130 percent of installed capacity, and the ongoing healthy traffic growth this operating rate is expected to rise further in the next 12 months.

“Operationalising of capacities in the following two fiscals will bring down utilisation levels albeit still high at over 90 per cent by fiscal 2023 and that is despite an unprecedented Rs 38,000 crore capex being undertaken by the operators of these airports over five fiscals 2020-24,” says the report.

Despite this unprecedented capex that is debt-funded, ratings are likely to be stable given the strong cash flows expected due to healthy traffic growth, low project risks associated with the capex and improving regulatory environment, notes the report.

“Capacity at these four airports will increase a cumulative 65 per cent to 228 million annually (from 138 million now) by fiscal 2023. However, traffic is expected to grow strong at up to 10 per cent per annum over the same period. Since additional capacities will become operational in phases only by fiscal 2023, high passenger growth will add to congestion till then,” warn the report.

High utilisation will ride on pent-up demand (accumulated in 2019 as traffic was impacted with the grounding of Jet Airways) and one-off issues with new aircraft of certain airlines.

Further impetus will also come from improving connectivity to lower-tier cities and reducing fare difference between air and rail. Increasing footfalls at airports provide a leg-up to non-aero streams such as advertising, rentals, food and beverage and parking, which comprise around half of the revenue of airports already.

These are expected to grow strongly at over 10-12 per cent, also supported by higher monetisation avenue coming along with current capex. The other half of revenue (aero revenue) is an entitlement approved by the regulator, providing a pre-determined, fixed return over the asset base and a pass-through of costs.

Aero revenue is also expected to get a bump up during fiscals 2022-24, when a new tariff order for airports is likely. Overall aggregate cash flows are likely to double by fiscal 2024 and provide a healthy cushion against servicing of debt contracted for capex, the report concludes.

New Delhi, Feb 27: An Indian Air Force aircraft on Thursday evacuated 76 Indians and 36 foreign nationals from the coronavirus-hit Chinese city of Wuhan.

The C-17 Globemaster III transport aircraft was sent to Wuhan on Wednesday and it carried 15 tonnes of medical supplies for coronavirus-affected people in China.

On its return, the aircraft brought back 112 people, including 23 citizens from Bangladesh, six from China, two each from Myanmar and the Maldives and one each from South Africa, the US and Madagascar.

Earlier, India had evacuated around 650 Indians from Wuhan in two Air India flights.

“In all 723 Indian nationals and 43 foreign nationals have been evacuated from Wuhan, China, in these three flights,” the Ministry of External Affairs (MEA) said.

On the medical supplies delivered by India to China, the MEA said they would help augment the country’s efforts to control the coronavirus outbreak which had been declared as a public health emergency by the World Health Organisation.

“The assistance is also a mark of friendship and solidarity from the people of India towards the people of China as the two countries also celebrate 70th anniversary of establishment of diplomatic relations this year,” it said.
